Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for resolving keystrokes. One of the methods includes receiving a first keystroke and a second keystroke input by a user on a keyboard. The first keystroke corresponds to a first key on the keyboard and the second keystroke corresponds to a second key on the keyboard that is different from the first key. The first keystroke and the second keystroke are determined to have been input at substantially the same time and the first key is determined to be adjacent the second key on the keyboard. In response to the determinations, a suggestion is generated that only one of the two keystrokes was intended to be input.

Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented touch screen user interface method that includes displaying a plurality of keys of a virtual keyboard on a touch screen computer interface, wherein the keys each include initial labels and a first key has multi-modal input capability that include a first mode in which the key is tapped and a second mode in which the key is slid across. The method further includes identifying an occurrence of sliding motion in a first direction by a user on the touch screen and over the first key. The method further includes determining modified key labels for at least some of the plurality of keys. The method further includes displaying the plurality of keys with the modified labels in response to identifying the occurrence of sliding motion on the touch screen and over the first key.

Abstract: The subject matter of this document can be implemented in, among other things, a method that includes displaying, on a user interface of a computing device, a base portion of a keyboard. The method further includes receiving, on the user interface, a user input that includes initiating a contact at a first region of the user interface that is associated with the base portion of the keyboard, moving the contact, while maintaining connection with the user interface, to a second region of the user interface that is outside the first region and that is associated with an extended portion of the keyboard, and releasing the contact at a location within the second region. The method further includes activating a selection in the extended portion of the keyboard based on the location within the second region at which the contact is released.

Abstract: A computer-implemented user interface method includes displaying on a touch screen a potion of a large scale graphical space that is at least multiples larger than the device display, receiving from a user of the device an input to pan within the graphical space, automatically generating a pop up graphical panning control in response to receiving the user input, and receiving a user input to the panning control and providing panning in the graphical space, wherein movement of the panning control in a single selection is able to pan the display across a substantial portion of the large scale graphical space.

Abstract: Methods and apparatus are provided for producing dynamic display characteristics on a container widget. One method comprises creating a container widget (210) including at least one child widget (230, 240) utilizing a document object model (DOM) (220). A first display characteristic and a second display characteristic are associated with the child widget, and a first event is attached to the container widget, wherein the child widget is displayed with the first display characteristic prior to the first event occurring and displayed with the second display characteristic if the first event occurs. The method may also include creating a child container widget having at least one grandchild widget utilizing a second DOM (260), associating a third display characteristic and a fourth display characteristic to the grandchild widget, and attaching a second event to the child container widget, wherein the grandchild widget is displayed in a manner similar to the child widget.

Abstract: A method and system is provided for customizing Java API implementations. A plurality of class files is obtained, wherein the class files are capable of being used together to provide a plurality of functional behaviors to an application. A feature marker is then associated with each of the class files based on a functionality provided by the class file.

Abstract: A method and apparatus for providing plug-in media decoders. Embodiments provide a “plug-in” decoder architecture that allows software decoders to be transparently downloaded, along with media data. User applications are able to support new media types as long as the corresponding plug-in decoder is available with the media data. Persistent storage requirements are decreased because the downloaded decoder is transient, existing in application memory for the duration of execution of the user application. The architecture also supports use of plug-in decoders already installed in the user computer. One embodiment is implemented with object-based class files executed in a virtual machine to form a media application. A media data type is determined from incoming media data, and used to generate a class name for a corresponding codec (coder-decoder) object.
